A stamping head 23 is fixed in the middle of the bottom surface;

所述机架10的顶板的顶面固定有主安装块12，主安装块12的顶面中部具有中部横向凹槽13，中部横向凹槽13的左右两侧底面具有下折弯槽14，中部横向凹槽13的底面中部具有主通孔15，主通孔15与中心落料通孔11上下对齐并相通，门字形的待加工板100压靠在中部横向凹槽13的底面上，待加工板100的左右两侧底面具有折弯部101，折弯部101插套在下折弯槽14中，冲压头23对着待加工板100；The top surface of the top plate of the frame 10 is fixed with a main mounting block 12, the middle part of the top surface of the main mounting block 12 has a middle transverse groove 13, and the bottom surfaces of the left and right sides of the middle transverse groove 13 have a lower bending groove 14. The middle part of the bottom surface of the transverse groove 13 has a main through hole 15, and the main through hole 15 is aligned up and down with the center blanking through hole 11 and communicates. There are bending parts 101 on the left and right bottom surfaces of the plate 100, and the bending parts 101 are inserted into the lower bending groove 14, and the stamping head 23 faces the plate 100 to be processed;

所述冲压板22的底面两侧固定有竖直柱221，竖直柱221的下端插套在压紧套222中，压紧套222中插套有缓冲弹簧223，缓冲弹簧223的底端固定在压紧套222的底板的顶面上，缓冲弹簧223的顶端固定在竖直柱221的底端面上，压紧套222的底面对着待加工板100。Both sides of the bottom surface of the stamping plate 22 are fixed with vertical columns 221, the lower ends of the vertical columns 221 are inserted into the compression sleeve 222, and a buffer spring 223 is inserted in the compression sleeve 222, and the bottom end of the buffer spring 223 is fixed. On the top surface of the bottom plate of the compression sleeve 222 , the top end of the buffer spring 223 is fixed on the bottom end surface of the vertical column 221 , and the bottom surface of the compression sleeve 222 faces the plate 100 to be processed.

进一步的说，所述压紧套222的底面固定有弹性防护层224。Furthermore, an elastic protection layer 224 is fixed on the bottom surface of the compression sleeve 222 .

进一步的说，所述机架10的顶板的顶面上固定有多个永磁铁柱16，永磁铁柱16插套在主安装块12的底面具有的安装孔中并与主安装块12相吸附，主安装块12的底面压靠在机架10的顶板的顶面上。Further, a plurality of permanent magnet columns 16 are fixed on the top surface of the top plate of the frame 10, and the permanent magnet columns 16 are inserted in the mounting holes provided on the bottom surface of the main mounting block 12 and are adsorbed with the main mounting block 12. , the bottom surface of the main mounting block 12 is pressed against the top surface of the top plate of the rack 10 .
